T 0 allwwm t may concer/a:

Be it known that l, Knaur/ iniNrv MEYER, a citizen of the United States, residing at Carlstadt, county of Bergen, and State of New Jersey, have invented certain new and useful improvements in Expanding Frames for Embroidery-Machines, of which the following isa speciiication.

This invention relates to an improvement in the detachable frames employed in embroidery machines to hold the fabric to receive the embroidery in a stretched position to have the pattern embroided thereon.

The inventionhas for an object to provide a novel and simple type of embroidery frame characterized by ease of application and removal of the fabric.

For further comprehension of the invention, and of the 'objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a face view of an embroidery frame constructed accord` ing to the invention.

Fig. 2 is an enlarged transverse section on the line 2--2 of Fig. 1.

Fig. 3 is an enlarged detail transverse section on the line 3-3 of Fig. 1.

Fig. 4 is a detail section on the line 4-4 of Fig. 41.

Fig. 5 is a detail horizontal section on the line 5-5 of Fig. 1.

Figs. 6 and 7 are fragmentary vertical sections illustrating the method of securing the fabric in place.

iis here shown my improved frame comprises the upper and lower main horizontal rails 1 and 2 which may be made of wood. rFliese rails are rigidly joined together by the vertical metal straps 3 which are bent at their ends as at 4f to project across the top and bottom faces respectively of the rails and may be secured thereto by screws or by any suitable means.

Disposed between and parallel to the rails 1 and 2 are a pair of intermediate bars 5 and 6 which extend behind and are secured to the straps 3 at their ends to slide longitudinally of the latter, or toward and away from the said rails. The means by which I secure these intermediate bars to the straps 3 is illustrated more particularly in Fig. 5 and comprises the metal strips 7 which are secured at one end by screws 8 to the front faces of the bars and have each a raised portion 9 which is spaced from the bars and projects over the vertical straps B. The other' ends of these strips are bent yback across the end faces of the bars as at 10 and iinally turned in behind the bars as at 11, screws such as 12 passing through, these inturned portions and into the bars. The bars are adjustably secured to the straps Sby means of headed pins 15 passing through suitable registering openings in the strips and the ends of the bars and through the desired ones of the series of holes 16 spaced longitudinally of each of the straps.

Extending along the upper rail 1 and sey cured thereto by screws 17 is a metal strip 18, this strip being mounted on the beveled off ,or inclined .lower portion 1 of the bar so that the strip is completely offset from the straps 3 The strip 18has an outwardly curved lower edge 418 to which is lfixed a row of pins 19 which extend upwardly over and parallel to, the. body of the strip.

A similar, and similarly arranged strip 20 is fixed by screws 21 to the adjustable intermediate bar 6, this strip. having the outturned edge 20 and upwardly projecting pins 22.

Extending along the adjustable bar 5 and secured thereto by screws 25 is an elongated clip member 26 which projects toward the top rail 1, this projecting portion being odset inwardly of the straps 3 and being doubled back upon itself as at 26. Within the channel formed in this clip member is inserted a fiat bar 27 having a rubber covering 28 which may be formedvby a rubber tube, this bar serving to hold the fabric in place as will be presently pointed out. A pair of latches 29 having their ends notched as at 291 are pivoted on the upper pair of strips 7 and are adapted to be swung into engagement with the projecting ends of the bar 27 to hold the latter in place.

Extending along the lower rail 2 is a second elongated clip member 30 this member being offset to clear the straps similarly to the strips 18 and 20 and clip member 26, and being secured in place by screws 31. The upper and lower edges of this clip member are doubled back as at 30 and 30a the doubled back portion a being shorter than the portion 30. A 'fiat bar 32, similar toV the bar 27, and having a similar rubber covering 33, is adapted to hold the fabric in this clip member. l

In securing on the frame a fabric to be worked, the top edge` of the fabric 34 is hooked on the pins 19 and the lower edge wrapped aroundV the rubber covered bar 27V the latter is then insertedinto position inv the clip member 26 as shown in Fig. 6 and the latches 29 swung to engage the ends of the bars 27. VThe bar 5 is then pressed down'- wardly along thestraps and Ywhen the fabric is properly stretched the pins l5 are. insertedinto placev through the registering ones ofthe holes 16. l

A different fabric 35 may be hooked atY its upper edge over the pins 22 and have its lower edge wrapped around theV rubber covered bar 32. The latter is then inserted in the clip V30 in the direction indicated by the arrow 36 in Fig. 7, the difference in length of the doubled back portionsBO and V30a permitting the bar to drop in past the portion 30a, the stretching Vof the fabric pulling the lower edge'of the bar down under said portion 30a, the upper edge being held by the portion 30. Y

It will'vbe understood that the main rails l and 2 may be of any suitable length and a series of frames arranged therealong.

The manner ofuse of the frame will be apparent from the'above description. When one frame is removed from the machineto have a new fabric stretchedv thereon, a second frame with the fabric thereon may be inserted in its place on the machine.

It is to be understood that I may combine or arrange the various Y fabric holding devices otherwise than as here shown, it not being essential that the clips 26 and 30 of fixed parallel rails, straps connecting said.4 rails, a bar extending between Isaid straps and secured thereto to be adjustable .therealong, and c. fabric A holding devices mounted on one of said railspand saidbar,

said fabric holding devices ,comprising an elongated clip member having one edge eX-v tendingbackwardly over the body thereof, y

a flatbar adapted to be inserted under the said backwardly extending edge,ra tubular rubber covering for said last mentionedbar, the said last mentioned bar being longen than the said strip and cover to cause the ends thereof to project therebeyondfand hinged latches mounted on the first mentioned bar and adapted to engage the projectingjends of the-second mentioned bar,

for the purpose A set forth.

In testimony whereof` Ihave affixed myk KATHARINE MEYER.
